Title: Device for mouth-inhaling aerosol medicaments
Inventor: CHIESI PAOLO
IPC: A61M11/00
Filed: 1991-09-11
Abstract: The invention provides a device for mouth-inhaling medicaments dispensed as aerosols by pressurized cans. The device is flat and compact in shape, comprises a seat for housing a can and defines an expansion chamber into which the aerosol dispensed by the can, when operated, penetrates and expands to circulate with a vortex flow which causes the solvent to evaporate and the flow movement to continue for a relatively long time, hence enabling only very small particles of the medicament to be drawn into the bronchial tree.        There is only minimum aerosol particle deposition on the walls of the oropharingeal cavity, and inhalation can continue after the entry of aerosol into the expansion chamber ceases.

Title: Expulsion of detrimental substance from theft-deterrent device
Inventor: HOGAN DENNIS L
IPC: H05K5/02
Filed: 1991-10-08
Abstract: In a device for deterring theft of a protected article, including a pin and clutch respectively embodied in two components that are adapted to be locked together on op-posite sides of a portion of the protected article to prevent unauthorized removal of the device from the article, the pin-containing component contains two fragile elongated glass vials that fracture when at least a predetermined pressure is applied thereto, with the vials containing a detrimental substance that would damage an article attached to the device if such substance were to be released from the vial; and the head of the pin includes a breaker element having a wedge-shaped surface of a fiber-loaded-reinforced thermoplastic, (which does not scratch glass), for applying more than the predeter-mined pressure against the vial In response to the pinhead being moved in response to application to the two components of at least a predetermined threshold separation force, to thereby completely fracture the vials by inducing a high bending stress without prematurely cracking the vials, and to thereby release the substance contained therein before the components are separated by prying or pulling the components apart.  A pli-able seal is disposed between the breaker element and the vials for preventing the detrimental substance that is released from the fractured vials from entering the head space and for expelling the released detrimental substance through the adjacent open-ing in response to pressure applied against the seal by the breaker element by the movement of the pinhead that results in the vials being fractured.

Patent CA-2062914-A1 (CA)
Inventor: BULLOCK DONALD F
IPC: G01R21/00
Filed: 1992-03-12
Abstract: A method of operating a meter to perform the steps of generating a measure of real energy consumed, generating a measure of reactive energy consumed, and generating, from the real energy and reactive energy measures, a measure of apparent energy consumed.      In one embodiment, the real energy and reactive energy measures are provided as integer quantity inputs. Particularly, assume S = kVAh, P = kWh, Q = kVARh, and R = Residue. Respective registers store values of P, [2P + 1], Q, [2Q + 1], and the sum [P2 + Q2]. Initially, the P, Q, and [P2 + Q2] registers are set to zero, while the [2P + 1] and [2Q + 1] registers are initialized to 1. At the arrival of a P pulse, the value in the [2P +1] register is added to the [P2 + Q2] register, then the P register is incremented by 1 and the [2P + 1] register is incremented by 2. Exactly the same steps are carried out subsequent to receipt of a Q pulse.      A set of registers also is used to store the S and [2S + 1] data, and generation of the S pulses is determined as follows. After arrival of either a P or Q pulse, a trial subtraction of [2S + 1] is made from the [P2 + Q2] register. If the subtraction does not cause an underflow, an S pulse is generated, the S register is incremented by 1, and the [2S + 1] register is incremented by 2. If the subtraction causes an underflow, the (P2 + Q2] register is reset to its previous value, the other registers are not incremented, and no S pulse is generated.

Abstract: The camera of the invention includes a magnetic recording head (30) adjacent the film (14) and a processor (32) which senses the lens focal length, the aperture size, the shutter speed and the film ISO number or film speed, and makes the following determinations: first, it determines from the scene brightness and film speed whether the ideal combination of shutter speed and aperture size, in terms of a required exposure value, falls within the range of maximum and minimum shutter exposure times and aperture sizes of which the camera is capable of providing, expressed in terms of a minimum camera exposure value and a maxi-mum camera exposure value. If the ideal exposure value for that scene falls outside the range of camera exposure values, then the processor causes a magnetic recording head (30) to magnetically record in or adjacent the current film frame a coded indication symbolic of the fact that the required exposure value was beyond the camera exposure value range.
